BUCKLE.

Application led December 16,1922. Serial No. 607,408.

To all who/m t may' concern Be it known that I, Nans T. NnLsoN, a

citizen of the United States, residing at improved buckle. s v

VFigure 2 is a front view of my improvedl Attleboro, in the county ofBristol and State of Massachusetts, have invented certain new and usefulImprovementsin Buckles, of which the following is a specification.

This invention relates to an improved construction of buckle moreparticularly adapted for adjustably connecting together the ends ofbands or straps for wrist vwatches and the like, but which may beemployed for any otherv purpose for which it is adapted; and the Vobjectofthis invention is vto provide a readily-removable bar for the buckleon which the buckle-tongue is `pivotally mounted, wherebythe bar may beremoved to receive the loop formed at the end of the' strap, and to also.facilitate the 're moval of this strap portion when Vworn to' bereplaced by afresh one.

W'ith these and other objects in View, the invention consists'of certainnovel features `of construction, asswill be more fully described, andparticularly pointed out in the appended claims. Y -f Y In theaccompanyingl drawings,

F igurel is a perspective view showing the back of a watch and the strapor band as attached to the watch with its free ends adjustably connectedtogether by means of my buckle showing a portion of astrap indottedllines as applied to the cross-bar thereof.

Figure l3 is anenlarged sectional elevation of my improved cross-bar.

Figure/i isan end section of my improved Vbar on line 4 4: of Figure 3showing the tongue as mounted thereon.v

Figure 5l is a perspective view of the cen-` ter spindle of my'barremoved. Y

Figure 6 is a perspective view of Voneof the end bushings of the barremoved;

Figure 7 is a perspective view of the outer shell of the bar.

Figure 8v is aside elevation of the gripping spindle retaining coilspring adapted to be mounted in the space in the bar formed to receiveit. f Y Y Figure 9 isV a modification showing the ends of the shellturned in to fornivbearings for the center spindle to take the place ofthe bushings,

It is found inV practice f of f advantageito provide a buckle of thetype described,'hav

.ing'a tongue to' enter' holes in thesti'ap or band for adjustablysecuring the ends of the bandV together, and itis also found' ofadvantage to provide a removableicross-bar in this buckle frame adaptedto be Yreadily reniovedto bev passed through the loop or eye formed inone end of the strap lto re'- ceive it, whereby the loop may berformeolkin the strap at the vfactory ready to be attached to the buckle withoutbeing obliged to sew or otherwise fasten the folded back and to securethe strap end aftery having been applied to the buckle; and the follow,

ing is a detailed description yof one means by which the removabilityofthe bar of the buckle frame maybeaccomplished vWith reference to thedrawings, l0 and Vll designate portions of a strap or band the oneherein shown being a wrist band worn more particularlyA by a man forattaching a timen lof the U-shaped buckle frame.v

Into each of the oppositeends of this shell, I force a shortrbushing 16,having'a central hole 17 and a centralspindleiS is mounted to extendthrough this shellfandv i through the openings in these bushingswith itsends projecting beyond those v of the. shell toreceive their bear-'ingsin the eyes of the i frame ends 13.

y `In order to frictionally retain this spindle in adjusted position inthe sleeveI have mounted a coil spring 19 in' the gspace between theinner ends of theybushing, the

same'having an internal diameterv of a size to grip the external surfaceof the;v spindle so thatwhen the spindle is forced through theV coil itis gripped and firmly yheld by all of y the multiplicity of itsconvolutions andas the ends of the spring abut against the oppositeinner ends of the bushings the spindle.

is held against endways movement except when considerable force isbrought to bear endways upon it.

In some instances I may, if desired,corru,.

misv

gate or roughen that portion of the surface of the spindle, engaged bythe .,coil, as illustrated at 2O in Figure 5, whereby the coil Will morefirmly grip the spindle and prevent relative @ndt/evs movement 0f thesame When'positoned in its Shell.

I do not Wish to be restricted to the insorting of separate andindependent bushing members into the ends of the shell as in some casesthe stock at the Ven dsof the shell -inay be turned inwardly to take theplace of the bushings and `form bearings for the center spindle.V v

The buckle tongue 2l yis provided With-an eye-22 ,tliroughivhich the,cross-bar is freely passed, the tongue being adapted to enter Yany ,ofYthe holes 23 in the strap to adjust the Samoa-bout the `Wrist 4of thewearer.

v In applying the strap to ymy improved buckle, the member 1l of thestra-p is preferabl-y provided with a loop 2li when made at the factory,as kshown in Figure l, by

Vfolding the extremity thereof back upon itself and :cement-ing,riveting or sewing this folded portion to thek body of the strap, and anopening or sli-t 25 is formed to receive the :tongue 2l.

norder to attach the strap to my improved buckle, it is only necessaryto force thespindle lSiout, remove the bar and insertwit With its tongueinto the loop of the strap, the latter may then be placed in line withYthe eyes'in the ends of the frame :and

the spindle forced through the shell, the spindle being'firmly retainedin its operatingposition by the grip of the coil until it is desired toagain remove it to replace the strap when Worn by a fresh one.V

'The foregoing descriptien is directed solely toivards the constructionillustrated, but I desire it to be understood that reservethe privilegeof resorting to allthe mechanical changes` to which the device issusceptible, the invention being defined and limited only by the termsof the appended claims.
